The bottom frame member consists of a main portion 4 having on each end a lug 38. The upper edge is bent outwardly or rearwardly to form a flange 40 and is then bent upwardly as at 42 at the same angle as the flange 28.

The frame rigidifying angle members 10 have their front edges bent downwardly to form a flange 44. The body portion is substantially in the shape of a right triangle, the hypotenuse being a plain edge. The flange 44 on one of the legs is cut away at an angle from the apex of the right angle as at 46. The other leg has a flange 48 which is bent back upon itself as at 50 to form a hook having an upwardly opening groove 52.

The glass holding frame comprises an upper portion 54, side portions 56 and a lower portion 58. Each of these portions is a channel member formed by bending sheet metal to channel shape. The upper portion 54 carries on its rear side a handle 60 to aid in operating the window. Each of the members 54 and 58 carries at its ends lugs 62 while the side members 56 have at their ends slots .64. The channels of the side members are slightly wider than the top and bottom members. These members are all adapted to fit on the edges of the glass 66 when the frame is assembled.

The latching means includes a portion 68 having a downwardly bent part 70 which fits into the groove 16 in the manner shown in Figs. 1 and 3. The portion 68 rests on the flange 18. At its outer end a latching member or bar '72 is pivoted thereto. This member carries on its outer end a weight '74 to cause it to hold the window securely. Its lower surface is provided with a plurality of corrugations '76, the corrugation '78 nearest the pivot being somewhat longer than' the remaining ones.

The parts of the window are shipped in unassembled condition to the user. In order to assemble the window, the side members 6 are first secured to the bottom frame member 4. The lugs 38 on the end of the bottom frame member are inserted through the slots 84 until the member 4 strikes the bottom of the groove between portions 26 and 32. The lug 38 is then bent over as shown in Figs. 11 and 12 to form the connection. At the same time, the portion 42 slides under the ear 36 to increase the steadiness and rigidity of the joint. The ear 36 may then be bent down tightly against the portion 42. It will be seen that when this arrangement is completed the flange 40 will close the bottom of the truncated pyramid formed by the cheeks 8.

Next, the top frame member 2 is added. The lugs 30 are pressed through the slots 24 and are turned down as shown in Fig. 1. The flange 18 then extends rearwardly beyond the flanges 26.

In order to strengthen the frame and particularly to add rigidity to the cheeks 8, the angle members 10 are used. In order to assemble these, the hook portion 50 is fitted into the groove 39 of the member 8. The angle member is then slid forwardly, while being maintained in an angular position (which is made possible by permitting the hook 50 to fit loosely in the groove 39) as shown inFig. 6 so that the cut away portion 46 passes above the flange 18. When the angle member reaches the position shown in Fig. 6, it is merely turned downward so that the flange 44 fits in the groove 16 of the top frame member 2. A tight and rigid joint is then provided.

The assembly of the glass holding frame is 1 likewise very simple. The top and bottom members 54 and 58 are first placed on the edges of the glass. The side members 56 are then slipped over the side edges of the glass so that the lugs 62 pass through the slot 64 (Fig. 10). The lugs 62 are then bent back upon themselves as shown in. Fig. 9 to form a tightframe.

It will be noted that the angle members 10 do not extend all the way to the rear of the cheeks 8. The glass' holding frame can therefore be slipped down within the flanges 28 until its bottom member 58 rests on the flange 48. The frame can now be swung backward and upward about its bottom as a fulcrum either to a fully opened position resting on the flanges 28 or to a closed position where it engages the flanges 26.

The flange '70 of the portion 68 of the latch member is now placed in the slot 16 (Fig. 3). This is located at the central portion of the window opposite the handle 60. By raising this latch member, the Window can be moved so that its frame engages different corrugations in the lower side of the latch 72 so that the window is held at varying angles. When the window is closed, the corrugation '78 engages the handle and pushes the glass holding frame tightly against the flanges 26. This is shown particularly in Fig. 3.

t will be seen that it is quite a simple matter to assemble this frame and that it can be done with a hammer and screw driver. When completed, the whole may be placed in any opening provided in a barn or other building as shown in Fig. 13, the portions 2, 4 and 6 being secured to the outer side of the building by nails or the like 80. 'The cheeks 8 then extend within the building and give indirect ventilation, and the flow of air therethrough can be adjusted as de sired.

While I have described herein one embodiment of my invention, I wish it to be understood that 1 I do not intend to limit myself thereby except within the scope of the appended claims.
